Specification of Letters Patent.

Patented Feb. 6, 191%.

Application filed August 22, 1914. Serial No. 858,107.

To all whom it may concern:

Be it known that I, VERNON ItorLn, a citizen of the United States, andresident of Paterson, in the county of Passaic and State of New Jersey,have invented a new and useful Cop, of which the following is aspecification.

My invention relates to a cop and more particularly to a cop for use inshuttles, with the object in view of providing a core sleeve cop with acore or spindle suitable for insertion into a shuttle to permit the copto freely unwind, the core being further provided with a clutch memberfor use in connection with winding thread thereon to reproduce a cop.

In the accompanying drawings,

Figure 1 is a view of the cop and its core in side elevation partly insection.

Fig. 2 is an end view of the same, and

Fig. 3 is a view of the core on which the cop is to be wound.

In the use of cops wound on paper tubular cores as has heretofore beencommon, when the cop is placed on the spindle within the shuttle,trouble has arisen from the sliding of the cop along the spindlecramping the thread and the paper core has further been subject toatmospheric changes, swelling in damp weather and contracting in dryweather. Furthermore, the core sleeve wound on the smooth surfacedspindle has not been found feasible because of the slipping of thethread thereon.

My present invention, therefore, is direced particularly to thestructure of the core which shall intimately coact with the core sleevewind to produce a cop and core combined, the core being of such a naturethat it may be rewound and used over and over again.

The body of the core sleeve wound cop is denoted by 1. The core is madeup of a spindle 2 provided with journals 3 and 4: at its opposite endsfor seating in suitable bearings in a shuttle, the said spindle beingprovided with a jacket or covering of such a nature that the thread ofthe cop 1 will not have a tendency to slip longitudinally along the corewhen it is wound thereon. The spindle 2 is conveniently made of steeland the covering is, in the present instance, a coarse thread 5 woundspirally thereon,

the successive spirals being in close juxtaposition but leaving slightindentations 6 between two successive spirals throughout the length ofthe core. The coarse thread 5 may be treated in any well known orsuitable way to render it proof against moisture or a nonconductor ofelectricity, and while I have shown the jacket or covering on the spindle as formed of threads, I do not wish to limit myself to a woundcovering, as my invention contemplates a permanent covering on thespindle 2 which shall produce a roughened or frictional surfacesuflicient to prevent the thread of the cop 1 from slipping out ofposition during the winding operation.

To fit the core ready for attachment to a winding machine, I provide aclutch member on each end of the spindle 2, in the present instance, byflattening a reduced portion 7 of the end of the spindle, as shown at 8.

To hold the jacket or covering 5 in position on the spindle 2, endsleeves 9 and 10 are driven on to the reduced portions 7 at the ends ofthe spindle against the shoulder 11, and the outer ends of said sleeves9 and 10 are cut away internally, as at 12, to leave room for the clutchmember, not shown, on the winding machine to slip over and co-act withthe clutch member 8 on the spindle.

By the above construction the core combines in itself a support for thecop during the winding of the cop and also during the unwinding of thecop without any shifting other than simply to place the cop and its corein position in the shuttle, and when the body of thread on the cop isused, the jacketed core may be used for winding another cop.

What I claim is:

1. A cop core comprising a cop receiving sleeve provided with aroughened surface to permit a coarse wind thereon and a spindleintimately united with the sleeve, the spindle being provided withjournals at its ends for use in a shuttle and with a clutch member foruse in a winding machine, whereby the core may be used both as a copreceiving and cop delivering element without change.

2. A cop core comprising a cop receiving sleeve provided with aroughened surface to permit a coarse wind thereon,- and a spindle, thespindle being provided with jouras my invention, I have signed my namein nals at its ends for use in a shuttle, with a presence of twoWitnesses, this twenty-ninth clutch member for use in a Winding machineday of July, 1914.

and With end sleeves for holding the cop re- VERNON BOYLE. 5 ceivingsleeve securely in position on the WVitnesses:
